Title: Guiding method for unmanned vehicle
Inventor: KOBAYASHI NAOYA
IPC: G05D1/02
Filed: 1988-02-05
Abstract: PURPOSE:To omit the allocation of marks, etc., by setting previously the polarization state for a magnetic guide line of an S pole from one side and a magnetic guide line of an N pole led from the other side which run in parallel with each other at a specific point on a guide path and detecting an unmanned vehicle at the specific point. CONSTITUTION:When an unmanned vehicle 10 is running on a guide path 2, an N pole sensor 12N of a guide line detector 12 detects a magnetic guide line 5 and transmits an N pole detecting signal VN. Then, an S pole sensor 12S detects a magnetic guide line 7 when the vehicle 10 enters a branch area 1 and the detector 12 reaches the passing position of a point P. The sensor 12S transmits an S pole detecting signal VS. A controller 11 receives both signals VN and VS and detects that the vehicle 10 reached the point P where the branch is started and reads the following guide path out of a map via the collation. Then, the controller 11 designates the signal VS received from the sensor 12S as a guide path detecting signal as long as the path read out of the map is equal to a guide path 3. Hereafter, the vehicle 10 picks up the guide path detecting signal and at the same time is guided by a guide line 7.

Abstract: PURPOSE:To prevent theft previously and to prevent an evil deed by providing an inclination sensor for detecting inclination and then outputting it as an electrical signal and an alarm device for generating an alarm when the output of the inclination sensor exceeds a certain inclination angle range. CONSTITUTION:A power input operation switch S1 is turned on and then a horizontal rotary switch S2, a vertical rotary switch S3. an angle measuring switch S4, a distance measuring switch S5, an automatic tracking switch S6, and a ten-key pad 32 are operated for performing survey.

When an outsider tries to move the survey machine 1 and hence the inclination angle of the survey machine 1 exceeds for example one degree, an alarm buzzer 33 rings. One the buzzer 33 starts ringing, it continues ringing unless the key K is engaged. Further, when the key K is pulled out of a switch 23, all of switches S1-S6 and the ten-key pad 32 are disabled. Therefore, even if the outside mischievously operates the operation switch of the survey machine 1, no influence is given to the survey machine 1.

IPC: F02D41/00
Filed: 1986-02-06
Abstract: PURPOSE:To reduce the speed change shock without incurring the rise of the exhaust temperature by correcting the quantity of fuel supplied into an internal combustion engine to the increased quantity side, when the ignition timing is corrected to the delayed angle side in the speed change of an automatic transmission for vehicle. CONSTITUTION:When speed change is performed by an automatic transmission M2 which performs the torque transmission from an internal combustion engine M1 to a driving wheel M3, an ignition timing correcting means M4 corrects the ignition timing of the internal combustion engine M1 which is set by other treatment further to the delay angle side, and the speed change shock is reduced. At the same time, a fuel correcting means M5 corrects the quantity of fuel supplied to the internal combustion engine M1 which is set by other treatment further towards the increased quantity side, and the rise of the exhaust temperature generated by the delay angle treatment is suppressed. Further, since the degree of the reduction of output due to the delayed angle of the ignition timing is larger than that of the increase of output due to the increased quantity of fuel, speed change shock can be reduced sufficiently.
